Remarks

To create a print support workflow, your app must declare a uap4:Extension element with the category windows.printSupportWorkflow in its package manifest that specifies the entry point of a background task. When the background task is activated, the IBackgroundTask.Run method receives an IBackgroundTaskInstance object. You can cast the TriggerDetails property of this object to a PrintWorkflowJobTriggerDetails object to get more details about the print workflow job session.

For more information, see Print support app design guide.

Properties

Methods

Events

JobStarting	Raised when a print job is started by a print workflow app. Your print workflow app can use members of the event args object to skip system rendering or modify the operation in other ways.
PdlModificationRequested	Raised when a document is sent to the print stack and Windows starts to convert the document to the page description language (PDL) format indicated by the printer. Your print workflow app can use members of the event args object to modify the conversion to the page description language (PDL) format indicated by the printer.
